Ski Season Readiness: Physical Therapy Exercises to Protect Your Knees and Back
Skiing is one of the most thrilling winter sports, but it also places tremendous physical demands on the body. Whether gliding through fresh powder or tackling steep slopes, skiing requires precise coordination, strong muscles, and resilient joints. Without proper preparation, the excitement of ski season can quickly turn into a painful experience involving knee strain or back discomfort.
The good news is that with targeted pre-season training and guidance from a physical therapist, skiers can strengthen the key muscles that support the knees and spine, improve flexibility, and significantly reduce injury risk.
This blog explains how to prepare your body for ski season, which exercises best protect your knees and back, and why a pre-season physical therapy program can make all the difference between a safe, enjoyable winter and time spent recovering indoors.
Why Ski Preparation Matters
The Demands on Knees and Lower Back
Skiing places intense repetitive stress on the knees and back due to constant bending, twisting, and absorbing impact from uneven terrain. The knees act as the main shock absorbers during turns and landings, while the lower back stabilizes the torso and helps transfer force between the upper and lower body.
If these areas are not properly conditioned before the season, skiers may experience instability, fatigue, or strain that can quickly lead to injuries.
Common Ski-Related Injuries
Recreational skiers often encounter:
ACL injuries: Caused by twisting falls or improper landing mechanics.
MCL sprains: From sudden side stress to the knee joint.
Lower back strain: Resulting from poor posture or weak core support.
Quadriceps or hamstring overuse: Due to excessive eccentric load during downhill runs.
These injuries often arise when strength, mobility, and control do not match the physical intensity of skiing.

How Pre-Season Training Reduces Joint Stress
A structured pre-season program focusing on strength, flexibility, and control prepares the muscles and connective tissues for the forces they will face. Strengthening the quadriceps, glutes, and core improves stability, while flexibility work allows the joints to move efficiently without excess strain. This preparation reduces joint stress, enhances endurance, and makes skiing both safer and more enjoyable.
Understanding the Demands of Skiing
Movement Patterns that Challenge Balance and Stability
Skiing requires coordination between the hips, knees, and core to maintain balance on an unstable surface. Frequent bending and rotating movements, especially when transitioning between turns, test the body’s ability to stabilize under load.
A skier’s balance depends heavily on:
Core engagement to maintain trunk control.
Hip strength to manage lateral movement.
Ankle flexibility to adapt to slope angles and equipment constraints.
When one of these areas is weak or restricted, it can throw off alignment and increase injury risk.
Importance of Eccentric Strength
Eccentric muscle strength refers to the ability to control movement as a muscle lengthens such as when the quadriceps slow the body down during a downhill run. Strong eccentric control in the quads and glutes helps absorb impact, stabilize the knees, and maintain control through turns and landings.
Without sufficient eccentric strength, skiers often experience muscle fatigue and knee strain early in their runs.
Building Strength Safely for Beginners
Beginners should start their conditioning program at least six to eight weeks before the season begins. Focus should be on foundational strength and body control rather than intensity. Exercises such as bodyweight squats, bridges, and core planks help build endurance and control before progressing to dynamic or resistance-based movements.
Top PT-Recommended Exercises for Skiers
Foundational Strength Builders
Physical therapists often recommend the following exercises to prepare for ski season:
Wall sits: Strengthen the quadriceps and mimic the semi-squat skiing stance.
Glute bridges: Activate glutes for hip stability.
Single-leg squats: Improve balance and correct side-to-side imbalances.
Lateral lunges: Train hip and adductor control for carving turns.
Romanian deadlifts: Strengthen hamstrings and protect the knees from overuse.
Before ski season arrives, setting a strong foundation matters. This video highlights simple, effective exercises you can start now to build leg and core strength for the slopes. A quick pre-season guide from Opus Physio on how to begin conditioning safely and progressively for ski season.
Stability and Core Control
Core stability is crucial for maintaining posture and managing quick movements on the slopes. Try incorporating:
Dead bugs and bird dogs for trunk stability.
Pallof presses to strengthen rotational control.
Plank variations to engage deep stabilizing muscles.
Drills for On-Slope Control
To simulate skiing demands, include dynamic movements such as:
Jump squats: Build power for take-offs and landings.
Skater hops: Improve lateral stability.
Balance board training: Enhance proprioception and ankle control.
These drills not only improve strength but also train the body to react quickly to changes in terrain.
Mobility and Flexibility for Injury Prevention
Importance of Hip and Ankle Mobility
Hip and ankle mobility directly influence skiing form. Tight hips limit rotation and make it harder to control turns, while stiff ankles reduce the ability to absorb shocks or maintain proper alignment with the boots.
A few key mobility drills include:
90/90 hip rotations: To improve internal and external hip movement.
Ankle dorsiflexion rocks: To increase joint range for smoother control.
Dynamic leg swings: To loosen hip flexors and hamstrings.
Stretching and Warm-Up in Cold Conditions
Cold weather reduces muscle elasticity, making an effective warm-up essential before hitting the slopes. Focus on dynamic warm-ups such as:
Walking lunges
Arm and leg swings
Light jogging or skipping
After skiing, gentle static stretches for the quads, glutes, hamstrings, and back help reduce tension and soreness.
Maintaining Flexibility During the Season
Consistency is key. Dedicate at least 10 minutes to stretching after each ski day. Foam rolling and mobility sessions during off-days can also help maintain range of motion throughout the season.
Preventing Knee and Back Pain on the Slopes
Common Technical and Muscular Mistakes
Most knee and back issues occur due to:
Over-reliance on the quadriceps with underdeveloped glutes.
Poor hip mobility leading to improper knee alignment.
Weak core muscles failing to support the lower back.
Correcting these weaknesses before the season helps distribute force more evenly and prevents overload on joints.
Knee pain is one of the most frequent complaints among skiers due to repetitive flexion, poor alignment, or muscle imbalance.

Posture and Stance Tips
Skiers should maintain a neutral spine and slightly flexed knees, keeping the chest upright but relaxed. The weight should be balanced evenly over the skis rather than leaning too far forward or backward.
Practicing this stance in pre-season drills can help train proper alignment automatically.
Building Stabilizer Strength
Stabilizer muscles, including those around the hips, knees, and spine, keep the body steady during high-speed movements. Strengthening these through single-leg exercises, balance work, and resistance band training helps protect joints from sudden force and misalignment.
The Role of Physical Therapy in Pre-Season Prep
Identifying Weaknesses Before the Season
A pre-season physical therapy assessment evaluates strength, flexibility, and alignment. This helps identify areas that may be prone to strain during skiing, such as weak glutes, tight hips, or poor core control.
Therapists can then prescribe exercises tailored to correct these deficits before they cause problems on the slopes.
Benefits of a Customized Conditioning Program
A personalized PT program ensures that every exercise and stretch directly supports skiing performance. These programs are designed around an individual’s body mechanics, previous injuries, and current fitness level ensuring safe, progressive improvement.
Ongoing PT Support During the Season
Even after ski season begins, physical therapy can help manage fatigue, recover from minor strains, and maintain flexibility. Regular check-ins allow therapists to adjust exercises, ensuring the body stays resilient and ready for continued performance.
Final Thoughts
Preparing for ski season is not just about strength; it is about building control, balance, and mobility that support every movement on the slopes. By focusing on knee and back health through guided physical therapy exercises, skiers can enjoy better performance, fewer injuries, and more time doing what they love.
A well-planned pre-season program, guided by a qualified physical therapist, can turn ski season into a safe, powerful, and rewarding experience no matter your skill level.
